DEVICE'FORAPPLYING CONTROL HEADS non WnLLsf Application ledvMarch 29, 1926.' VSerial 110.9?,209

K'My present inventionhas reference to a' devicefor use in connection with oil or gas wells, and my object is the provision of means for facilitatingthe arrangement of control heads on flowing wells.

Y A further object ,is the provision of a device for this purpose characterized by simplicity in construction, and reliability and efficiency in practical use. j p

To the attainment of the foregoing, the inventionA consists in the improvement as hereinafter described and definitely claimed.

In the drawings:

Figure 1 is an elevation ofthe ment in applied-position.

Figure 2 is a bottom plan View thereof. .,*Figure' 3 is afragmentary side elevation with parts in section.

Figure 4 is aside elevation, to more clearly ilustrate. the arrangement of parts before the improvement is swung to bring the control head in a position to be coupled to the casing collar.V

Referring now to the drawings' in detail, the numeral 1 ldesignates a portion of a well casing, and 2 a collar which is screwed thereon. VThe well is flowing', and I liX on the casing 1 a clamp of a particular and peculiar construction and which is broadly indicated by t-he numeral 3. The clamp includes two removably associated sections, each having its central portions rounded outwardly to provide a round opening for the clamp. Each of the sections, from its said rounded portion, has outwardly extending arms 4 and 5, respectively, and these arms are connected .together by removable means 6. The section provided with the arms 5 has its rounded portion Aformed with an arm .extension 8 arranged at a right angle with respect toits arms 5. The arms 5 terminate in short rounded extensions or shafts 9, andV mounted on these shafts 9 there are the eye ends 10 of rods 11. The rods are engaged by turn buckles 12, the outer ends of the said turn buckles having threaded therethrough rods 13 whose threads are at Opposite hand pitch to those of the'rod 11. The upper or outer member of the improvement is somewhat similarly constructed to that of theclamp 3, the same including a central rounded portion 14 having oppositely extendingarms 15 provided with short shafts 16 to receive the eyes 17 of the rod or bolt members 13. Cotter pins 18 pass through the short shafts improve- 9 and 16 for holding the bolts of the turnV buckleson said shafts. VEither integrally formedy with or welded in the rounded portion 14 of the upper member or clamp 19 there is a collar 20. yThis collar is of a greaterlength than ordinary collars; the desirability'of such length collar will presently be apparent.

Extending outwardly from the rounded portion14 of the member 19,A in the same direction as the arm 8 extends'from the member 3, there isan arm 21.

' The member 19is swung with the turn-buckles onthe trunnions 9 and there is screwed into the special collar 20 aV nipple or pipe 22. v,This nipple is also screwed into theV casing of the control head oryvalve y23. Screwed in the opposite end of the said control head or valve there is a second and preferably shorter nipple 24. The nipples 22 and 24 are effectively secured inthe casing of the control head or valve 23, thevsame being preferably welded to thek said casing, so thatthenipples and casing will turn in unison. The nipple 22 has its outer end threaded for a comparatively ,great length and the said nipple is wholly or almost wholly screwed into thecollar 20. An elevator, or any other suitable means is now employed for swinging the device to vertical position which brings the threaded end of the nipple 24 above the collar 2. To hold the nipple 24A in positivealignment with the collar I secure, by means 25 and 26 to theA outer ends of the arms 8 and 21, the bifuroated ends of oppositely hand pitch threaded rods27 and128 which are engagedby a turn buckle 29. The control head, including' the nipples22 and24, is bodily turned to back the nipple 22 out of the special collar 20 and bring the sleeve 24 in threaded engage# ment in 'the'collar 2. Of course, the'turn buckles 12 and 29V may be adjusted to facili-` tate the backing of the control head out of the collar 2. During the placing of the control head on the casing 1, the valve 23 is opened, but after the control head is firmly slecuied on the well casing the valley may be c ose l With my improvement it will be noted that control heads may be easily, quickly and accurately coupled to flowing wells. The rounded body portion of the lower clamp underlies the collar 2, and the. turn buckle arrangement'between the clamp 3 and the l outer member 19, which may be also termed a clamp, not only Vproperly centers the conthe rods of trol head when being screwed into the collar 2, but materially strengthens `the control head or valve when the same is subjected to the pressure of the flowing fluid from the well. ln the outer endvof the collar 2O there is screwed a pipe line extension 30.

Adapted for contact with the nipple 24 there is what I will term a clamp member 50. This clamp has oppositely extending arms l which have their ends fixedly secured to the rods ll. rlhis will prevent the pressure from turning th-e device upside down when it is being swung into place.

lt is believed that the simplicity of my construction and the advantages thereof, will be perfectly apparent to those skilled in the art t-o which this invention relates, when the foregoingr description is read in conection with the accompanying drawings, but it is to be understood that l do not Wish to be restricted tothe precise details of construction herein set forth and hold myself entitled to make all such changes therefrom as fairly -fall within the scope of what I claim without departing from the spirit or sacrificing any of the advantages of theinvention.

Having described the invention, I claim l. An apparatus for applying contr-ol heads to flowing wells, inclu-cling a clamp fixed on the upper end below and in contact with the top collar of a well casing, a mem ber having an elongated collar in the center thereof, threaded throughout its length and in which one of the nipples of the control head is fully screwed, swingable means connecting the clamp with the said member, a

brace between the clamp and member removably attached to these elements when the member has been swung to bring the lower nipple of the contr-ol head opposite but in a line with the collar of the well casing.

2. The combination with a well 'casing having a collar on the outer end thereof, designed to have screwed therein a control head, of a device for applying the control head to the clamp, said device comprising a clamp arranged on the well casing below and in contact with the collar, and a member disposed opposite'the clamp and carrying a central sleeve of a comparatively great length and which is threaded throughout and which is designed to have screwed therein the'outer end of the control head, adjustable means piv-otally connecting the clamp and the membenand removable adjustable means adapted te be connected to the clamp 'and said member when theV device has been swung to bringl the control head in a position to be backed off of the last mentioned collar and scewed into the well casing collar.

3. The combination with a casing of a 'flowing well hai/'ing a collarscrewed on the outer end thereof, of a means for threadedly securing a control head in the collar, said means comprising` a lower clamp, made up of 'two removably associated sections, and having` a rounded porti-on to receive the casing theretnrough and to contact with the under face of the collar, said clamp lhaving oppositely extending parallel arms whose ends are formed with trunnions and having another arm arranged centrally thereon and at right angles with respect to the first mentioned arm, an outer clamp having a central elongated collar which is threaded through-l out the length thereof and having oppositely extending parallel arms whose ends are formed with trunnions and having a central outstanding arm arranged at right angles with respect to the first mentioned arms, oppcsitely hand pitched bolt members having eye ends received on the trunnions of the respective clamps, means holding the bolt members on the trunnions, turn buckles connecting the members, the outer nipple of the control head designed to be first screwed into the last mention-ed collar prior to the swinging of the device toV a vertical position to arrange the lower nipple of the control head over the nipple of the well'casing, oppositely pitched rods designed to beA connected to the central arms of the clamps when the .device is in its last mentioned position and a turn buckle engaging said rods.

ln testimony whereof, l affix my si nature.
